Howdy again, I started thinking that it was odd that my RPMs did not go up in mourning even though the cold start injector is working correctly, also I thought it was odd when I cranked the LC Pro Tunning module to rich that this did not increase RPMs another 200 too 300rpms like it should. Basicaly what could cause the tail pipe to look rich and truck to have a erractic miss and when you poor more gas in by the 2 methods above you get know increase in RPMs I would think this would be narrowing it down some, does it sound like ignition?

Thanks!
